0 rattle and which will prevent the sash from rattling or becomingdisplaced when open or partially open and which will not interfere inany way with the operation of the upper and lower sashes of the window.

Another object is to provide a sash holder of the type above described,which includes highly efficient frictional means associated with a pairof pivoted links, whereby the storm sash may be adjusted to a desiredopen position by merely swinging the lower edge thereof outwardly orinwardly as the case may be, the frictional elements securely holdingthe sash against rattling and displacement.

Still another object is to provide a compact sash holder which may beeasily and conveniently attachedto conventional storm sash and windowframes now extensively used and which is provided with a highly iefficient attachment bracket secured upon the 0 the invention will'befully set forth in the following description made in connection with theaccompanying drawings wherein like reference characters refer to similarparts throughout the several views and wherein, Y

In the drawings, aaconventionaltype yof window-frame is shownhaving asill S, the

usual blind stop Band other elements coin-V storm sash Xis ofaconventionaltype and is swingably connected at its upper edge by strapsor eyes Y 'to .hooksZ securedto the upper' jamb of the window frame. Thelowthe storni sash may be swung to open or vclosed position. y My sashholders eachcom- .prise a pair of kpivoted links associated withy thestormlsash andthe window frame (usually the blind stop of Vthewindowframe) for adjustably holding the storm sash 'in a desired open positionand .for'permitting the sash to be entirely closed .flush against theare used for each installation aiidsince the devices are identical, for.the purpose of brevity, only one thereof 4will be described.

The said device comprises ya pair` of flat mon in most typesof-vwiiidfow frames. The

ler member or railof the storm sash Xis .L provided with a suitablehandle H by which vblind stop. ,Ordinarily two of these` devices i links10 andrllrespectively, pivoted togetlier by suitable means', suchas arivet .12, adjacent their. :inner ends. `The `outer link l0 projectsatits inner extremitysome distance beyond the pivot 12 carries aresilder tension by the rivet 12 nwhich extends nient clip4 13 bowedslightlyandclampedun- 1'# through the approximate center thereof.

`Clip 13 may be constructed of suitable resilient material and isprovided at each of its ends and along its longitudinal edges withinturned projections forming two pairs of straddling members forengaging the longitudinal edges of link 10 adjacent the pivot to preventoscillation of the clip upon the link. Three of said inturnedprojections are numbered 13a and terminate inwardly of or at least flushwith the inner surface of link 10. The upper projection numbered 13badjacent the extremity of link 10 is projected beyond the longitudinaledge of link 10 in order to engage and abutY the longitudinal edge oflink 11 when the links are swung outwardly into longitudinal alinement.This positively holds the links extended in a straight line with thestorm sash opened to its full limits with my device applied. The link 10at its outer end is pivoted by suitable means, such as a rivet 14, withthe out-turned ear of a small angle bracket 15 having an attachment basewhich is secured by suitable means, to a point at one side and adjacentthe lower rail of the storm sash X. The link 11 is detachably pivoted toa small and compact bracket 16 which is secured to the window frame andpreferably to the side of the blind stop B. Bracket 16 comprises avertically disposed plate having adjacent the upper portion thereof ashort projecting stud or pin 16a which is adapted to receive the end oflink 11 passing through an aperture 11a formed in said end, and aretaining lever 17 is pivoted by a rivet 18 to bracket 16 at a pointbelow pin 16a, said lever having a relatively short and slightly Yoffset end 17a which is adapted to engage and slide over the outer endof pin 16a and the outer surface of the connected end of the link 11,preventing displacement of the link from the bracket while permittingpivotal movement of the link 11 upon the pivot pin. The handle end 17 bis elongated to permit the lever to be easily manipulated for attachingor detaching my storm sash holder from the window frame.

When the storm sash is fully closed against the blind stop B, the links10 and 11 will be swung together and superimposed in the positionshownby the dot-ted lines in Fig. 1, and to assist in holding the links insuperimposed position, and thereby prevent accidental opening of thestorm sash, I may provide a small projection 11b on one of the linksadapted to register and interlock with va detent 10a formed in theappropriate surface of the other link, when the links are 'swungtogether in fully closed position.

The links 10 and 11 are preferably formed of metal or material havingsome resiliency and the links may be swung apart by apply- 'ing slightforce.

The clip 13 in addition to limiting the outward swinging movement of thelinks and holding the links in longitudinal alinement also yieldinglyforces the pivoted ends of the links into frictional engagement, sincethe resilient clip is under considerable tension supplied by the rivet12. The flat opposed surfaces of links 10 and 11 adjacent the commonpivot afford considerable frictional area and the structure with theclip is so efficient that the storm sash may be held frictionally in anyopen position between closed position and the fully open positionillustrated in the drawings, without the addition of other clamping orlocking means. To open or' close the storm sash, assuming the links 10and 11 to be out of longitudinal lalinement, it is only necessary tograsp the handle H and swing the storm sash to the wardly.

In connecting or disconnecting the inner link 11 with the bracket 16,retaining lever 17 is swung slightly out of vertical position `whereuponthe apertured end of link 11 may be engaged with or disengaged from thepivot stud 16a. It will be seen that with this readily detachableconnection, the storm window may be readily installed upon or detachedfrom the window frames.

Vhen the storm windows are detached, the links 10 and 11 are folded uponeach other and swung compactly against the frame of the sash Whereafterthe storm windows may be stacked or piled conveniently.

It will be seen that with my device, no part of the links or otherelements ever project inwardly in the path of the upper and lower sashesof the window.

From the foregoing description, it will be see that I have invented anextremely sim ple and improved storm sash holder, which may bemanufactured at very low cost, which will be effective to hold a .stormsash in a variety of diiferent open positions and by which the stormsash may be adjusted without releasing hooks, clamping devices or othermeans. The frictional conection between the links, connections of thelinks with the attachment brackets, as well as the fact that the linksare relatively short prevent the devices and the storm window fromrattling or working loose.

It will, of course, be understood that various changes may be made inthe form, details, arrangement and proportions of the parts withoutdeparting from the scope of my invention, which, generally stated,consists in adevice capable of carrying out the objects above set forth,in the novel parts and combinations of-parts disclosed and dened in theappended claims.
